Paint for aluminum siding

A100 in my opion is a builders grade paint, only has a 15 year warrenty.
If you looking to sell and just want something painted it will work.
Super paint comes with a life time warrenty, cost more to buy but worth it.http://www.sherwin-williams.com/home...oatings/paint/

Having to go back years later and paint it all again just to save a few bucks now does not make since to me.

Resilience has the advantage of being more moisture stable during application so the threat of rain is less of a big deal when your painting. And it's a good quality paint.
The main thing will be to make sure the aluminum is clean, and free of chalk. On a sound surface, any of your choices will work good.

Generally a good cleaning will suffice. Run the palm of your hand over the surface. if chalky residue sticks to your hand, that residue will new to be removed or stabilized before painting.
Aluminum is bad to chalk, especially if its never been painted. I have seen several disastrous paint failures caused by painting over chalk. The paint will bond with the chalk instead of the surface, and literally fall off over time. There was a recent thread where this exact thing happened to someone.
Pressure washing is ok, aluminum is pretty fail safe as far as washer damage, but pressure washing alone often won't remove all chalk.
Scrub the surface with a soft brush, along with washing with a pressure washer, or just a garden hose. The scrubbing is the key. If you have chalk, it will look like watery milk as it washes off the house. After washing, do another palm test to make sure all the chalk is removed.
I've seen chalk so bad that even after thorough wash/scrub some still remains on the surface. There are also additives that help paint bond to chalky surfaces. 'Emulsabond' is the most common one that I know of.
My personal favorite for dealing with chalk is 'Seal Krete Original' it can be used as an additive or as a primer to stabilize chalk. But it can be hard to find.
Good luck!

We paint a lot of alluminum siding around here and every company I have ever worked for swears by emulsabond. It really is the cat's meow for making paint stick to chalky surfaces.
